LTC1293/LTC1294/LTC1296
Unipolar conversion is requested and the data is output
MSB first. CS is driven at 1/64 the clock rate by the CD4520
and D
OUT
outputs the data. The output data from the D
OUT
pin can be viewed on an oscilloscope that is set up to
trigger on the falling edge of CS (Figure 24).
